“The experience of weight occurs through that contrasting force of the ground that pushes you back as you push on the ground, because gravity pulls you down. If you are in a spaceship you don't feel the weight because you don't have the ground pressing down on you." (2)On the other hand, if you travel towards the center of the Earth your weight in Newtons will not increase – like the force of gravity it actually gets smaller! Keep in mind that your mass is still the same. Hypothetically, though, if you were right at the center of the Earth, you would have forces pulling in every direction, and as a result the net force would be zero because all the forces they cancel and balance each other… so you will be weightless, so to speak
